  • Patent number: 8962696
    Abstract: The invention provides a method and a composition for enhancing the dissolution and bioavailable properties of propofol (2, 6 diisopropyl phenol) for use as an intravenously administered anesthetic in mammals. The method produces a self-microemulsifyable emulsion base composition that is utilized in the production of a water-based microemulsion preparation. In a preferred two (2) component base composition, the base composition consists of: a surfactant, containing polyethylene glycol; and liquid propofol. The microemulsion is prepared by mixing the base composition with a carrier liquid, which results in the formation of a microemulsion containing concentrations of propofol of up to about 4% by weight of propofol to the volume of the microemulsion. In a four (4) component base composition, the base composition consists of: a surfactant, containing polyethylene glycol; liquid propofol; a water-immiscible solvent; and ethanol.

  • Patent number: 7767195
    Abstract: A high throughput neurophysiological assay for identifying anti-psychotic compounds is disclosed. In particular, a high throughput neurophysiological assay using information obtained from injecting a neural activity blocker, such as tetrodotoxin (TTX), into one hippocampus persistently coactivated pyramidal cells in the uninjected hippocampus that initially discharged independently. In accord with the definition of cognitive disorganization, pyramidal cell firing rates only changed for 15 min and did not accompany the coactivation. The disclosed assay uses the TTX-induced coactivity of hippocampal pyramidal cell discharge to identify compounds that may prevent or attenuate the changes in the hippocampal pyramidal cell discharge observed when a neural activity blocker is administered. The assays of the invention are useful for high throughput screening of targets in the discovery of drugs that have anti-psychotic properties.

  • Patent number: 7030100
    Abstract: Several lines of evidence have shown a role for the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signaling pathway in the development of spinal hyperalgesia. However, the roles of effectors for cGMP are not fully understood in the processing of pain in the spinal cord. cGMP-dependent protein kinase (PKG) I? but not PKGI? was localized in the neuronal bodies and processes, and was distributed primarily in the superficial laminae of the spinal cord. Intrathecal administration of an inhibitor of PKGI?, Rp-8-[(4-Chlorophenyl)thio]-cGMPS triethylamine, produces significant antinociception. Moreover, PKGI? protein expression was dramatically increased in the lumbar spinal cord after noxious stimulation. This upregulation of PKGI? expression was completely blocked not only by a neuronal NO synthase inhibitor, and a soluble guanylate cyclase inhibitor, but also by an N-methyl-D-aspartate (NMDA) receptor antagonist, MK-801.
